Question

我正在尝试将Huey用作跨平台任务队列。我发现了https://github.com/pjcunningham/flask-huey-example，我已经克隆并设置了一个虚拟环境来使用conda（我正在Windows上工作）。我遵循了更新的自述文件，并设法使所有三个窗口正常运行。但是，当我打开http://localhost:6060/

时

我点击发送按钮，这中断了Huey_consumer进程：

如何使它正常工作？

Answer 1

尝试启动Visdom服务器时出现完全相同的错误：

OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions

原因是，还有另一个进程使用与Visdom要使用的端口相同的端口，在我的情况下是端口8097。

要对此进行调试，请按照以下步骤操作：

使用TcpView from Sysinternals使用端口查找进程。
如果该过程为svchost.exe，则需要查找使用此端口的服务。为此，请运行以下命令：`tasklist / svc / FI“ PID eq 1234”，其中从TcpView中看到的PID代表1234。
打开Windows服务小程序并查找此服务器。在我的情况下，这实际上是“交付优化”或DOSvc服务，如果您在大型网络上，则该服务基本上使用Windows Update位的P2P下载。我暂时关闭了该服务，并能够再次打开端口。

发生这种情况是因为您的防火墙阻止了SQL Server的连接。转到Control Panel -> Windows Defender Firewall -> Advance Setting -> Outbound规则（Block network access R local）为红色-> right click -> Properties，然后依次为allow all connection和Save
